Conservation officers said 65-year-old Robert Scanlon, and his wife, Candy Neville, of Shaker Heights, Ohio, decided to take the Ammonoosuc Ravine trail back down Thursday.

Officers got a rescue call at about 8:30 p.m. Scanlon had experienced pain in his knees, which slowed them down and hindered their ability to complete the hike during daylight. The couple hadn't brought flash lights and they were dehydrated. They couldn't continue to the base of the mountain.

Officers hiked up the trail, found the couple, then escorted them down to their car about 10:15 p.m.
